Nitrobenzene is used as a solvent and as a starting material in the organic synthesis for the preparation of aniline, benzidine, azobenzene, nitrosobenzene, phenylhydroxylamine and acetaminophen. It is also used as a solvent for electrophilic reagents in synthetic chemistry. Further, it is used to prevent the unpleasant odor in shoe, floor and metal polishes. It acts as a precursor to rubber chemicals, azo dyes and pharmaceuticals.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
Applications
